TMPRSS2 and Infertility: Meanwhile, through reducing dynamical expression of Furin, TMPRSS2 and ACE2 for multiple protection of susceptible cells (Figure 3), 3D‐E/BSC prevents the virus from invading other types of cells expressing ACE2, thus helps eliminate various potential sequelae such as infertility and brain aging, yet with no negative impact on myocardial cells and vascular morphology indicating normal functioning situation of cardiovascular or other relative system.
